The schools principal estimates that the current environment of 790 students will increase by 3% each year for the next 10 years. By what percent well the enrollment increase over 10 years?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

c. side angle side. u shares the same sides
